In this example, the Particle Component has been used as an explosion. With each click, a new component is created. To create the explosive effect, the emit rate is a very fast 5 milliseconds. At this rate, the component is emitting about 200 particles a second. To keep things reasonable, the explosion is limited to 30 particles.

The result is a momentary, explosive creation of high velocity particles in a fraction of a second. Everything happening at once - as it should be.
